How to Convert Gigabytes to Bits
To convert gigabytes to bits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. Try the b to GB conversion rate.
GB is a byte-based unit used for measuring file sizes and storage capacity. You might also need: converting Gigabytes to Terabits.
b is a bit-based unit—multiply bytes by 8 to get bits. You might also need: Kilobytes in Bits.
1 GB = 8,000,000,000 b (using SI decimal standard) — which means there are 8,000,000,000bits in every gigabyte.
GB to b Conversion Formula
// Convert GB to b
b = GB × 8,000,000,000
// Reverse: Convert b to GB
GB = b × 1.250000e-10
GB to b Conversion Examples
100 GB = 800,000,000,000 b
256 GB = 2,048,000,000,000 b
500 GB = 4,000,000,000,000 b
1,000 GB = 8,000,000,000,000 b
2,048 GB = 16,384,000,000,000 b
What Is a Gigabyte?
A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Check out our EB to YB.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: TB/s to PiB/s converter.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Related: GB to PB calculator.
1 GB = 8 × 10⁹ bits = 1 × 10⁹ bytes.
The gigabyte can be abbreviated as GB; for example, 1 gigabyte can be written as 1 GB.
What Is a Bit?
The smallest unit of digital information, representing a single binary value of 0 or 1. You might also need: convert PB to b.
The bit is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: MB → Mb.
Common uses: Network speeds, data encoding, processor architecture (32-bit, 64-bit) See also: Tebibits Per Second to Megabits Per Second.
1 b = 1 bits .
The bit can be abbreviated as b; for example, 1 bit can be written as 1 b.
